quantum cryptography path-breaking

Abstract : Seminar Quantum cryptography in path breaking allows to distribute a secret key between two distant parties using the basic principles of quantum mechanics. The paradigm of the famous mechanisms of quantum key distribution based on the actual transfer of the particle signal through a quantum channel. In this letter, we show that the task of a secret key distribution may occur if a particle carrying secret information is not actually transmitted over the quantum channel. The proposed protocols of quantum cryptography path-breaking can be implemented with current technologies offer practical benefits of security by eliminating the possibility that eavesdroppers can directly access the entire quantum system each particle signal.
